Draw or write two ways to use a doubles fact to find 6+7

1 answer:

4 0

Here are a few doubles facts:

5+5=10
2+2=4
3+3=6

A double is simply a pair of identical numbers added together. There's a pair of doubles you can subtract 1 from to get 6+7, and there's a pair you can add 1 to get the same answer. What are those pairs?

Hint: If you take the example 3+4, you can either subtract 1 from the double 4+4 or add 1 to the double 3+3 to obtain your answer.

Which rule should be applied to reflect f(x)=x^3 over the y-axis?

Given f(x)=x^2+12x+26 .

lapo4ka [179]

f(x)=x^2+12x+26

Vertex form of f(x) = a(x-h)^2 +k

We change f(x) into vertex form using completing the square method

$f(x)=x^2+12x+26$

We take half of square of middle term

middle term is 12

Half of square of 12 is $\frac{12}{2}=6$ then 6^2 = 36

Add and subtract 36 to complete the square

$f(x)=(x^2+12x+36)+26-36$

$f(x)= (x+6)^2 +26 - 36 f(x)= (x+6)^2 -10$

The vertex form $f(x)= (x+6)^2 -10$

HELP ME

Alrighty, so, if I remember correctly: For the first question you have 20 possible outcomes, 4 of which are multiples of 5. (5,10,15,20). This gives you 4/20, I multiplied both the numerator and denominator by 200 which then gave me 800/4000. Next I divided which gave me 0.2.
